I'm a few days behind on the tournament, spotted something odd.
Usually the rules say that you're required to wear a headset until your entire team is eliminated, to keep you from overhearing comms by other nearby teams.
Buriram wasn't.
They showed it at the beginning of the game: https://youtu.be/dVrJSmnQi20?t=13282
And again near the end: https://youtu.be/dVrJSmnQi20?t=14684
Did they have an exception? Or just sloppy operation of the tournament, like https://old.reddit.com/r/CompetitivePUBG/comments/1ofmq6y/buriram_get_caught_using_nvidia_profile_inspector/ ?
